SMF58A

LGE · ESD And Surge Protection (TVS/ESD) · SOD-123

SMF58A from LGE, in a SOD-123. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode of the unidirectional TVS, marked by the color band on the package; connect to the protected line, with VRWM 58 V and breakdown 64.4 to 71.2 V at 1 mA.
2 A passive Anode of the unidirectional TVS (end opposite the color band); connect to ground or the return, with maximum clamping voltage 93.6 V at IPP 2.14 A.

  • Symbol: SMF58A
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: smf58a-etched.step / smf58a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf58a.step / smf58a.glb are the bare package body.
